Airbricks – Box 20

These Timloc cavity wall vents are a standard fix for ventilating suspended timber ground floors and providing airflow through external walls. Fitted into the outer leaf of a cavity wall, they work alongside underfloor vent systems and cavity sleeves to pull fresh air under the floor and keep the subfloor space dry and well-ventilated. That matters a lot more than people give it credit for — a poorly ventilated subfloor is a fast route to timber decay and damp problems that are expensive to put right.

Buying in a box of 20 makes sense for new builds, extensions, or any project where you’re installing a run of airbricks along the base of an external wall. The volume pricing saves you making multiple trips to a builder’s merchant for a handful at a time, and having spares on site is never a bad thing.

Cavity Wall Vent Colour Options

Getting the colour right is one of those details that matters once the job is done and the client is walking round the outside of the building. These airbricks are available in Black, Blue and Black, Brown, Buff, Grey, Terracotta, and White, which covers the range of common brick and mortar tones well. Select the closest match to your brickwork before ordering — it takes seconds and avoids the awkward conversation about why the vents stand out like a sore thumb.

The louvred face design allows airflow while offering some resistance to pest entry and driving rain. They’re sized to fit standard brick courses, so installation is straightforward when the coursing is planned correctly during the build or when cutting out and replacing existing blocked vents on older properties.
